Abstract
-
Vasculitis is a rare complication of antithyroid drugs. Recently it was reported in
association with ANCA. In most cases, the ANCA was specific for myeloperoxidase. The
glomerulonephritis was key clinical manifestation in majority of cases. When antithyroid
drugs were discontinued, clinical disease generally improved and ANCA titers were tended
to fall. We experienced a 44 year old woman who presented with gross hematuria and
generalized edema, after she had been treated with prophylthiouracil for 6 week for
thyrotoxicosis. Renal biopsy was done, which showed mesangial proliferative
glomerulonephritis. Indirect immunoflurorescence staining showed highly positive
perinuclear pattern of ANCA in her serum. Prophylthiouracil associated ANCA positive
glomerulonephritis was suspected. After cessation of prophylthiouracil and administration
of prednisolone, renal function recovered gradually and ANCA titers were reduced.
We hereby report a case of prophylthiouracil associated ANCA positive glomerulonephritis
with a brief review of literature.
